Medically reviewed.
Syprine (trientine hydrochloride) is a prescription copper-chelating medication used to treat Wilson disease. It binds excess copper and helps your body remove it through the urine. This lowers the copper that builds up in your body and helps prevent progressive liver and neurologic damage. Doctors often prescribe it for people who cannot tolerate penicillamine. Treatment decisions should always be individualized and guided by a healthcare professional.
This page covers Syprine in Wilson disease care: how it works, who may be prescribed it, how it is used, benefits, side effects, and monitoring. You can also connect with a liver specialist near you for personalized guidance on your care plan.

ABOUT SYPRINE TREATMENT
Syprine is a prescription medicine that contains trientine hydrochloride. It is a copper-chelating medication. "Chelating" means it binds to copper so your body can remove it.
Syprine treats Wilson disease, a condition in which excess copper builds up in the body. It is commonly prescribed for people who cannot tolerate penicillamine, or as another long-term chelation option.
Syprine comes as oral capsules. Your provider pairs it with a low-copper diet and regular monitoring, such as Liver Function Tests.
WHO SYPRINE MAY BE SUITABLE FOR
Your healthcare provider may prescribe Syprine if you have Wilson disease and cannot tolerate penicillamine, need long-term copper chelation therapy, or have excess copper that needs treatment.
This fits what liver guidelines describe. The European Association for the Study of the Liver (EASL) states that initial treatment for people with Wilson disease symptoms must include a chelating agent, either D-penicillamine or trientine.
Every patient's health profile is different, so there is no one-size-fits-all answer. Your provider decides whether Syprine fits your care plan after assessing your liver condition, copper levels, and other medicines.
ELIGIBILITY OVERVIEW
Syprine may be considered for adults with the following conditions or treatment needs:
Before recommending Syprine, healthcare providers evaluate several factors to decide whether it is appropriate, including:
HOW SYPRINE CAN HELP YOUR BODY
Syprine binds, or chelates, excess copper in the body. It forms soluble copper complexes that leave your body in the urine. Over time, this reduces your total body copper stores.
In Wilson disease, too much copper can injure the liver and the nervous system. By lowering copper, Syprine helps prevent that progressive liver and neurologic injury. It supports long-term management of the disease.
Syprine is not used on its own. Providers pair it with a low-copper diet and regular monitoring, such as a 24-hour urine copper test.
LIVER BENEFITS
In Wilson disease, extra copper builds up in the body and can injure the liver. Syprine binds this copper and forms soluble complexes that leave your body in the urine. Over time, this lowers your total body copper stores, which takes pressure off the liver.
The Liver Therapies Patient Guide lists liver protection as a key benefit of Syprine. By lowering copper, it reduces copper-related liver injury and helps protect the liver and the nervous system. Results vary from person to person.
Copper that keeps accumulating can cause liver injury to worsen over time. Syprine helps prevent this progressive liver injury. It supports long-term management of Wilson disease and helps keep the disease from progressing.
Syprine may support liver health by removing excess copper, reducing copper-related liver injury, and helping prevent further liver damage. Benefits depend on taking it as directed. A qualified healthcare professional should start and monitor your treatment.
TREATMENT PROCESS
Syprine comes as oral capsules. Take it exactly as your healthcare provider directs.
Typical doses range from 750 to 2,000 mg a day, divided into 2 to 4 doses. Your healthcare provider adjusts the dose based on your copper levels, how you respond, and your clinical status.
Take Syprine on an empty stomach, at least 1 hour before or 2 hours after meals. Separate it from iron supplements by at least 2 hours, because iron may reduce absorption.
Syprine is used as long-term, often lifelong, therapy in Wilson disease. Your provider keeps adjusting treatment based on your copper balance and how stable you are. Do not stop taking it without talking to your provider.
Store Syprine at room temperature, away from moisture and heat.
Regular monitoring of liver function, complete blood count, kidney function, and 24-hour urinary copper excretion is recommended. Report any side effects or unusual symptoms to your healthcare provider.
BENEFITS AND SAFETY
Syprine may help people with Wilson disease by removing excess copper, reducing copper-related liver injury, and helping protect the nervous system. It supports long-term control of the disease. Benefits vary from person to person. Syprine works best as part of a broader care plan that includes a low-copper diet, avoiding alcohol if you have liver disease, and regular monitoring, such as liver function tests and a 24-hour urine copper test.
As with any medication, Syprine may cause side effects. Your healthcare provider will discuss the potential benefits and risks before treatment and adjust your care plan as needed.
BENEFITS
In Wilson disease, copper builds up in the body over time. Syprine helps in four main ways, and the benefits are strongest when you take it as directed and keep up with monitoring.
Syprine is a copper-chelating medication. It binds excess copper and forms soluble copper complexes that leave your body in the urine. Over time, this reduces your total body copper stores. Your provider tracks progress with tests such as a 24-hour urine copper test.
Some people cannot tolerate penicillamine. Syprine gives them another way to receive copper chelation therapy, so treatment can continue. Your provider decides which option fits your health and treatment goals.
Too much copper can injure liver cells and affect the nervous system. By lowering copper, Syprine helps reduce copper-related liver injury. It may also improve or stabilize neurologic symptoms. Results vary from person to person.
Wilson disease needs lifelong management. Syprine is used as long-term, often lifelong, therapy. It helps prevent the disease from progressing when you take it as directed. Your provider adjusts your treatment over time based on your copper balance and how stable you are.
Your healthcare provider will discuss the potential benefits and risks before treatment and provide ongoing support, including regular monitoring, to help ensure safe use. Contact your provider if you notice any of these effects or other unusual symptoms.
SUPPORTING YOUR TREATMENT
Syprine works best as part of a broader plan. A low-copper diet, avoiding alcohol if you have liver disease, and regular monitoring are an essential part of care alongside your medication.
Sticking with your therapy and monitoring is essential for keeping copper under control over time.
